Apparatus for non-invasive forced oxygen enrichment of avian eggs

ABSTRACT

Apparatus, methods, and products are disclosed in which an egg is noninvasively infused with oxygen such that the structural integrity of the shell of the egg is not compromised. The method comprises the step of subjecting the external surface of the egg shell to the oxygen under a condition of at least one of vacuum and positive pressure. The oxygen is from a substance selected from the group consisting of oxygen, nascent oxygen, liquid oxygen, oxone, ozone, hydrogen peroxide, and potassium permanganate.

This application is a continuation pending application Ser. No.08/746,903 filed Nov. 19, 1996 which is a continuation-in-partapplication of application Ser. No. 08/485,091 filed Jun. 7, 1995, nowU.S. Pat. No. 5,598,807.

BACKGROUND OF THE INVENTION

In non-extinct species, the avian egg is known to range in mass from0.25 to 1,500 grams. The common poultry egg has an average weight ofabout 60 grams. The common fertilized poultry egg is both self-containedlife support system and cradle. However, the life support system isflawed. It lacks oxygen. All other elements are present, including thefuel with which the fire of life will be sustained through thetwenty-one day journey.

Oxygen is the driving force which feeds the biological matrix from whichthe new life is fashioned. The cycle of synthesis begins at the moment"set" occurs, i.e. the moment that the process of viability is initiatedwhen the temperature of the fertilized egg exceeds about 680 F to about700 F for any substantial period of time.

From the first moment the process of viability begins, the margins ofsuccess are tenuous. A race between catabolic and anabolic processes isinitiated as life force courses forward. Oxygen must be obtained and theapparatus for gathering it must be fashioned within the margins of thesmall reserves available. Never again will the challenge be quite sogreat or the margins so small. The slightest unfavorable environmentalconditions, and the battle is lost.

Unfortunately, the optimal conditions for incubation also favor internalcompetitive breakdown forces and external invasive ones. Idealconditions in the incubator, darkness, moderately high humidity andtemperatures of 99.50 F±0.50 F are nearly optimal for microbial lifewhich will proliferate around and inside the egg shell. Thus, amultitude of foreign life forms are present. Some may be innocuous,others competitors or antagonists, and it is even possible that somefamiliar types such as Salmonella are symbiotic to the avian neonate.

The viability processes begin at the center but are subsequently focusedoutward to the extremities of the egg. Surrounding the embryo is alaminar set of membranes. The outermost layer (actually, a bi-layer)lies against the shell. The innermost layer is referred to as thechorioallantoic membrane and envelopes the albumen and yolk.

The outer shell is made up of crystalline calcium and is many timesthicker than the inner shell and other adjacent membranes combined. Theexternal surface has trumpet-shaped pores which run through the shell tothe surface to the membrane. Typically, there are about 7,000 to 17,000pores distributed over the shell surface, the highest density being atthe rounded end (top) of the egg proximal to the air sac locatedadjacent to the interior of the shell. The air sac is a space created bya parting between the outer and inner shell membranes wherein the outermembrane remains attached and the inner (chorioallantoic) membrane isdetached from the outer shell membrane. The separation between the twomembranes creates the air sac which serves as a gas exchange depot,sometimes referred to as the "dumb" lung. The dumb lung respires inresponse to changes in temperature and atmospheric pressures. The dumblung also grows larger and larger as the ovum takes up less and lessspace in using up its reserves, the byproducts of which pass through thelung to the outside. Once incubation has started, the embryo provides anetwork of arteries and veins to the working side of the lung, whichthereafter allows for efficient gas exchange through the lung.

Prior art teaches that as pressure is applied and then increased tofertilized eggs, fatalities from the onset of pressure very quicklyincrease to 100%. Prior art also teaches that as vacuum is applied andthen increased to fertilized eggs, fatalities from the onset of pressurevery quickly increase to 100%. Furthermore, prior art shows that whenambient oxygen is increased or decreased above normal concentrations(21%) during incubation, the hatch rate of fertilized eggs decreasesmarkedly. In sum, prior art shows that there is no known advantage toany process applied to fertilized eggs prior to incubation, and thatfertilized eggs are adversely affected by such treatments.

Handling and artificial incubation methods have developed over the lastcentury to create the best known conditions of humidity, aircirculation, stable storage and incubation temperatures, and motion toprovide maximum hatch of fertilized egg stock. For storage of fertilizedegg stock, air sac (top) up for no longer than twenty days at atemperature of about 550 F is preferred. For incubation, air sac (top)up, humidity of about 60% during the first 18 days and about of 70% thelast three days, a temperature of 99.50 f+0.50 F with a gentle,cradle-like rocking motion, timed about once every ninety minutes, andfiltered, recirculated ambient air (21% O₂) is preferred. Theseconditions result in more or less maximum average hatches. Percentagesof average hatches vary considerably depending upon the storage age offertilized egg stock and the age, type and conditions of laying flocksfrom which they are derived. In general, the range is from about 80% tounder 86% hatch, or a 14% to 20% mortality less the percentage ofunfertilized eggs.

Shortly after hatching, chicks are injected with vaccines (such asMarek's) to prevent flock diseases. Significant expense and mortalityare incurred due to the invasive nature of the injection.

Improvements in the overall healthiness of the hatched chicks stronglyinfluences efficiencies with respect to grow-out factors of the flock,i.e., percentages of grow-out mortality, size, strength, fertility, feedconversion, susceptibility to disease and, ultimately, overallcommercial success of the flock as layers, breeders or broilers andfryers for meat. Improvements related to better disease resistance, feedconversion, strength and increased commercial success from grow-out arealso desirable. Finally, the ability to provide early nutritionaladvantages, to provide medications related to improved mortality orgrowth, to alter or manipulate sex characteristics, to provide microbialsynergists (probiotics), to control disease agents, including those ofpoultry and those pathogenic to humans, is also desirable.

SUMMARY OF THE INVENTION

Oxygen as defined herein includes O (oxone), O₂, O₃ (ozone) or anyconvenient source thereof including liquid oxygen, hydrogen peroxide andpotassium permanganate, all of said chemicals above defined asoxygen-bearing chemicals.

Fertilized egg as defined herein includes both fertilized andpre-fertilized eggs (ovum)--also referred to as "vital eggs"--of anybird egg including chicken, turkey, goose, duck, raptor and parrot.

The present invention encompasses treating fertilized eggs prior to andin prenatal incubation phases by methods employing one or more ofcombinations of pressures, vacuums and above ambient levels of oxygen inthe form of O₂ and/or O₃, or sources thereof, to non-invasively transferthe O₂ and/or O₃ through the egg shell without compromising thestructural integrity of the shell.

When used according to the present invention to achieve the purposes asoutlined, ozone exhibits vitalizing, as opposed to expected lethalproperties, endowing the ovum with remarkably improved strength. Thisnot only results in significantly higher survivability throughincubation, but also greater strength through adulthood.

Contrary to the prior art, it is in the period of incubation and beforethe egg has developed oxygen-collecting organs or respiration thatforced oxygen/ozone treatment demonstrates the most profound overallresults. Increased hatch of fertilized eggs may be obtained by oxygenenrichment, preferably forced, and most preferably when the treatment isapplied prior to or soon after incubation starts, with the oxygen beingsupplied into the egg spaces and interstices--even in high concentrationlevels which would normally be considered lethal concentrations.Non-invasive oxygen augmentation may be accomplished in a variety ofways, including subjecting fertilized eggs to brief periods of vacuumsand/or pressures in the presence of oxygen or oxygen-containingsubstances or earners.

Non-invasive but forced perfusion of disease control vaccines offertilized eggs, with or without simultaneous forced enrichment ofoxygen, can also provide profound benefits in terms of reduced mortalityand cost savings of inoculation. More certain inoculation andsubstantial reductions in hatchling injection mortality occur.

Additionally, non-invasive forced perfusion of growth, health and gendercharacteristic additives, such as aromatase, may be added with orwithout enriched oxygen, affording valuable benefits to treated hatchedflocks including important "out of the shell" disease and infectioncontrol, improved growth, feed conversions and added overall robustnessand vitality.

Moreover, the levels of enrichment required to improve survivability offertilized eggs also endow the chicks with greater robustness, as shownby better feed conversions over the grow-out period. The result is muchhigher efficiencies of production. Feed conversion is a composite resultwhich may be comprised of one or more other operative factors such ashealthier, stronger, less diseased or more disease resistant chicks.

Also, the microbicidal effects of oxygen against poultry endemicbacteria, such as Salmonella, are realized; particularly if more activeforms such as nascent and ozone oxygen are increased in the oxygenenrichment treatment. Finally, the present invention provides improvedfood safety, for it is axiomatic that healthier animals providehealthier, safer food products.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT I. OVERVIEW

A. Oxygen:

Application of oxygen may be calculated as any equivalent mole weightabove atmospheric concentrations (20.946%) supplied to the fertilizedegg. Oxygen includes allotropic forms, nascent oxygen, liquid oxygen andoxygen-containing compositions such as hydrogen peroxide (H₂ O₂),potassium permanganate (KMnO₄), and the like. Mole weights, calculatedas percentages of the oxygen in enrichment fluid supplied to thefertilized egg, may be calculated as O₁ (oxone) at mole weight 7.9997,O₂ (oxygen) at mole weight 15.9994, and O₃ (ozone) at mole weight47.9982.

For purposes of increased hatchability of fertilized eggs, the workingrange of enrichment oxygen calculated as O₂, O₃ or a combination thereofwhich may be employed is from greater than ambient, and is from about21% to about 99.9998%. The preferred range of oxygen is from about 25%to about 99.99%. The most preferred percentage of oxygen is 45%±4%. Whenreduction of indigenous microbes is the object, or an added object, thepreferred range is from about 50% to about 95%, and the most preferredoxygen concentration is about 70%±5%.

For hatchability, the oxygen may be high purity oxygen or a mixture ofhigh purity oxygen (O₂) and ozone (O₃) as liquids or gases. Oxygensources may also be selected as hydrogen peroxide, potassiumpermanganate solution and other fluidized oxygen carriers. A mixture ofO₂ and O₃ are preferred, from about 1 to about 250 parts per million ofO₃ to O₂.

For hatchability and microbial control, a mixture Of O₂ and O₃ may alsobe used, with O₃ in the range of about 10 to about 5,000 parts permillion Of O₂. A ratio of about 100 parts per million O₃ to O₂ ispreferred. Though not preferred, H₂ O₂, O₂ and O₃ may also be used incombination, or H₂ O₂ may be used as an adjunct or treating agent inranges of from about 0.001% to about 30% in aqueous solution. About7%±about 4% is preferred. Aqueous solutions of potassium permanganatemay range from about 0.001% to about 20% in aqueous solution, but arepreferred in lower concentrations, i.e., about 3%±about 2%.

Oxygen working range by weight compared to weight of egg is about 0.0001grams to about 20 grams per 1,000 grams of egg mass. As stated, theoxygen may be from any source, such as liquid oxygen, purified oxygen,oxygen or ozone dissolved or associated with water or other carrier(s)or solute(s), including but not limited to ambient air as an ozonecarrier. The preferred range is from about 0.001 to about 9 grams per1,000 grams of egg mass. The preferred amount is about 3.0 grams per1,000 grams of egg mass. Where oxygen or an oxygen source alone is usedas the treating agent or in a carrier (usually but not always one orboth of air or water), the concentrations may range from more thanambient (21%) to about 99.9998%. The preferred range is from about 60%to about 99%. Some other preferred levels of oxygen as treating agent oringredient thereof are: when applied as a gas including available oxygenin carrier, about 95%; when applied as a liquid with carrier(s), about50%; when applied as a super-cooled or liquid gas, about 99.8%; whenapplied as a super-cooled liquid or gas containing at least 1 part permillion ozone, about 99%; when applied as hydrogen peroxide solution,about 60%; and as hydrogen peroxide and/or permanganate solutioncontaining at least I part per million ozone, about 70%. Ozonatedmixtures of oxygen are the most preferred enrichment media.

B. Negative Pressure:

Fertilized eggs may be subjected to negative pressure at the externalsurface of the egg. One method is to place the egg in an enclosed plenumupon which is exerted negative pressure to create a vacuum. Vacuums areapplied externally to the egg in order to create room within the egg forthe oxygen, and to force enriched forms of oxygen(s) and/oroxygen-carrying substance(s) through the shell upon relief of negativepressure. Enrichment capacity of the egg is enhanced by disinfusing thevacuum of ambient gases previously present in internal spaces and asdissolved gases in the egg matter. This step is followed by judiciousintroduction of the selected oxygen enrichment mixtures into thevacuumized plenum and consequently into the egg, which is also in astate of negative pressure. Alternative methods of treatment may also beused, though the underlying principles remain operative.

The above method of treatment permits optimization of the maximumconcentration of selected enrichment gases into the egg. Such means canbe accomplished by pathways other than using a chamber or vessel. Forexample, the egg may be warmed to cause internal expansion, resulting inexpelling of ambient internal gases, and then cooled in the presence ofselected enrichment gases, whereupon the egg will take in enrichmentgases and replace at least some of the original ambient gases present.Also, liquid oxygen, preferably containing ozone, may be applied by finespray to the pores of the egg surface to infuse oxygen. Another exampleis to employ a pressure cup, such as a suction cup, which can be affixedby contact to the external shell surface, preferably immediately overthe air sac where poration is at maximum density. By applying negativepressure vacuum through an aperture in the suction cup, the air sac andother portions of the egg are emptied of indigenous gases. Oxygen andother treating agents may then be infused through the shell pores bynegative pressure and/or in a positive pressure stream. While notessential to minimal oxygen enrichment, treatment vacuums are preferredwhen gases alone are employed. An exception to the use of vacuum iswhere the available oxygen or other treating agent is in a liquid orassociated with a carrier, such as liquid oxygen, hydrogen peroxidesolutions or potassium permanganate in aqueous solution, as examples. Inthese instances, a positively pressurized fluid stream containingperfusate alone may be directed across and forced through the poresadequately. However, as a rule both negative and then positive pressureare preferred steps.

The working ranges of vacuums which may be employed are from greaterthan ambient to about 29.99 inches of mercury for a short time period.The time range for application of preferred vacuums from ambient toabout 29.50 inches of mercury is from about one second to twentyminutes. The preferred vacuum range is from about 2.00 inches of mercuryto about 29.99 inches of mercury. The preferred time range forapplication of the above preferred range of vacuum is from about one toabout ten minutes. The preferred vacuum, if no added pressure cycle isemployed, is about 28.00 inches of mercury ±1.5 inches of mercury. Thepreferred time at preferred vacuum, if no added pressure cycle treatmentis employed, is about one and one half minutes ±one minute. If apositive pressure cycle also is to be applied to the egg, then thepreferred vacuum is still about 28.00 inches of mercury ±1.75 inches ofmercury for about one and one half minutes ±one minute.

Generally, the time to achieve the elected vacuum may range from aboutone second to twenty minutes. Preferred times to achieve elected vacuumsfor all preferred ranges is from about thirty seconds to about tenminutes. Preferred time to achieve vacuum is about three minutes ±1.5minutes. If a given vacuum is achieved too quickly, such as 29.90 inchesof mercury in one second, physical damage can occur to some eggs. Theopposite is true for the time over which the vacuum is held. If held toolong at higher vacuum ranges, e.g. above about 27 inches of mercury fortwelve to thirty minutes, the unabated vacuum may cause damage to someeggs.

Negative pressure may not be required for lower efficiency treatment;positive pressure alone may be adequate. Of course, the reverse is alsotrue. Where lower efficiency treatment is acceptable, however, positivepressure is usually preferred since it alone fills the air sac. All butthe most modest (approximately three inches of mercury to sixteen inchesof mercury) negative pressure treatment will collapse the air sac andthe air sac can only be refilled by at least a small (approximately fiveto ten pounds per square inch in a plenum) positive pressure step.

C. Positive Pressure:

Positive as well as negative pressure without oxygen kills fertilizedeggs. If positive and/or negative pressure is applied for a sufficienttime period or at high or low enough pressure, even added oxygens willnot prevent egg fatalities. The working range of positive pressureswhich may be employed are from slightly greater than ambient (about 3pounds per square inch) to about sixty pounds per square inch for fromabout one second to about thirty minutes. The preferred range ofpressure is from about two pounds per square inch to about thirty-fivepounds per square inch for from about one second to about ten minutes.The preferred pressure and time is about fourteen pounds per square inch±three pounds per square inch for about one and one half minutes ±oneminute. The preferred pressure ranges when a vacuum is also employed arefrom about three pounds per square inch to about twenty pounds persquare inch for from about four minutes to about fifteen minutes, butranges of from about two pounds per square inch to about thirty-fivepounds per square inch from about one second to about ten minutes areacceptable. Preferred pressure with vacuum is about fourteen pounds persquare inch for about two minutes. Working ranges for pressure whenapplied to an oxygen-bearing fluid stream are from about twenty fivepounds per square inch to about 150 pounds per square inch, and whenapplied to fluid stream bursts from about 100 pounds per square inch toabout 1,500 pounds per square inch.

II. SPECIFIC EXAMPLES Example 1

Referring to FIGS. 1 and 8, fertilized eggs were force-enriched withoxygen as follows. Five hundred twenty eggs were treated and fivehundred twenty were kept as controls. The average weight of the eggs was60 grams ±5 grams. Sixty-five eggs were in each treatment, and the totalnumber of treatments was eight. Bottled oxygen (99.8%) waspressure-regulated for delivery to the treatment vessel at 32 pounds persquare inch through a UV ozone generator (7.5 watt, 2,537 Å bulb) and UVchamber (7-inch diameter×14-inch length). The ozone generated fromoxygen was 0.5 grams/cubic meter of oxygen at 32 pounds per square inch.Sixty-five eggs were placed in the pressure vessel and sealed. Thevacuum level was selected to be 28.5 inches of mercury with elapsed timeto full vacuum being 2.5 minutes. At 28.5 inches of mercury, evacuationof the chamber was stopped and the eggs were held for five minutes. Theequilibrated oxygen in the UV chamber at thirty-two pounds per squareinch was slowly fed into the egg vessel to restore ambient pressure. TheO₂ /O₃ continued to be fed into the chamber for about ten minutes untilthirty-two pounds per square inch was achieved. The thirty-two poundsper square inch was held for five minutes. Immediately thereafter, theexhaust valve of the pressure vessel containing the eggs was opened andthe oxygen and ozone were exhausted until the chamber achieved ambientpressure. The time from the exhaust of pressured oxygen/ozone to ambientpressure was approximately one minute. The eggs were removed from thechamber and the process repeated seven times until five hundred twentyeggs had been treated per test. After removal from the chamber, the timefrom the process until the eggs "set" in the incubator ranged from fiveto one hundred twenty minutes.

After hatch, both the treated and control chicks from Group No. 11 werethen transported to a grow-out facility where feed consumption and bodyweight were monitored weekly.

Feed consumption is typically calculated based on the amount of feednecessary to increase the bird weight by one pound. This is referred toin the industry as the feed conversion ratio. Efficiencies in feedinghave increased so dramatically in recent years that there is little roomfor improvement. However, industry estimates indicate that even smallreductions in the feed conversion ratio measured to the second decimalpoint are significant, and can represent substantial savings to thepoultry producer. Results of the feed conversion analysis are listed inthe table below.

Example 2

Of 1,728 fertilized eggs, 576 were held as controls and 288 weresubjected to a vacuum of 29.8 inches of mercury for ten minutes,pressurized to ambient with filtered air only, and then placed in anincubator as shown in FIG. 2 and FIG. 9.

Another 288 fertilized eggs were placed in a pressure chamber forfifteen minutes with filtered ambient air only at 28 pounds per squareinch and then placed in the same incubator as shown in FIG. 3 and FIG.10.

Another 288 fertilized eggs were subjected to both 29.8 inches ofmercury vacuum for 10 minutes and pressurized with filtered ambient aironly for fifteen minutes at 28 pounds per square inch as shown in FIG. 1(but without UV generation of ozone) and FIG. 8.

Another 288 fertilized eggs were subjected to vacuum of 29.8 inches ofmercury for ten minutes and immediately pressurized with O₂ /O₃ forfifteen minutes at 28 pounds per square inch. A mixture of 99.6% pureoxygen was flushed across a 35 watt UV (2,537 Å) light until the ozoneconcentration measured by an ozone monitoring device was 4.5 grams percubic meter of O₂. This mixture was flooded into the vacuum chamber torelieve the vacuum over a period of eight minutes and then allowed topressurize the vessel to 28 pounds per square inch over a period offifteen minutes as shown in FIG. 1 and FIG. 8.

The average increase over control was about 3.5%.

This test shows the profound effect Of O₂ /O₃ when added to the vacuumintake. (Compare these results with the test results in which O₂ /O₃ wasnot employed.)

Example 4

Example 3 was repeated except that only ambient air was drawn into thevacuum intake with no oxygen/ozone, see FIG. 2 and FIG. 9.

Vacuum treatment alone of fertilized eggs without the benefit of oxygen,and particularly ozone, results in significant increased mortality whencompared to the controls.

Example 8

Test 1

Non-invasive injection of hydrogen peroxide solutions through the shellpores of fertile eggs results in significant hatch increase.

500 milliliters of an 8% solution of hydrogen peroxide was added to thereservoir of a 3 milliliter capacity peristaltic delivery pump attachedto a plastic-tipped nozzle five inches long by 1/4 inch in diameter witha bore of approximately one millimeter. The pump line pressure duringthe positive phase measured sixty-five pounds per square inch.

The increased hatch at use levels of potassium permanganate was about2.5%.

Example 10

A Jamesway model 252 incubator 10 was modified in accord with FIG. 6.Specifically, the incubator 10 was reinsulated with 1.5 inch R-90insulation sheets 12 and made air tight by the addition of seals 14 andsilicone caulking along all open seams or leakage points such thatpressures of up to 35 PSI can be attained. Tightly closeable dampers 16and 17 were fixed in the ambient air inlet 18 and outlet 20 lines sothat all incoming or outgoing ambient air could be sealed off by closingor opening the dampers. The condensate exit line 22 was affixed to aknown-in-the-art positive displacement pump (not shown) whichautomatically emptied condensate when humidity increased above 56%±2%for the first eighteen days and 58%±2% for the last three days ofincubation. The condensate pump activated at 58% and 60%, respectively.Oxygen and ozone humidity probe 24 (Cole Parmer humidity/temperaturetransmitter, Model H-37402-00, 4 to 20 ma output, RH 20-95%±2%,temperature 400 to 1300 F), air pressure probe 26 (0 to 100 PSIA, 1 to 5volt, manufactured by Cole Parmer), carbon dioxide probe 28 (Cole ParmerCO₂ meter), and temperature probe 30 (type K thermocouple attached to astrawberry tree analog data acquisition board). Data acquisition wasrecorded every ten seconds and stored in process data monitor 32 (anIBM-compatible computer). Automatic controllers were operated forhumidity and temperature compensation. Oxygen and ozone were monitoredand physically increased or decreased by opening or closing an oxygenregulator valve 33 connecting incubator 10 to oxygen source 34, and byactivating or deactivating the UV ozone generator module 36 (2537 /).CO₂ build-ups were sorbed in an in-line impingement scrubber 38containing 10% KOH and water to limit CO₂ build-up to no more than 0.5%.Oxygen source 34, ozone generator module 36 and scrubber 38 are allconnected to air recycle line 40, along with air compressor 42 (0 to 250rpm, 1 cc bursts, 7/16" Tyson Peristaltic variable speed pump). Airrecycle line 40, in turn, communicates with recycle inlets 42 in thebottom of incubator 10 and recycle outlets 44 in the top of incubator10.

The test used one thousand eggs as subjects and one thousand ascontrols. Both the control and the test incubators were modified to thesame specifications except the control incubator was fed from a twohorsepower compressor through an adjustable air regulator. Air intakefrom the compressor was first filtered through a charcoal and fiberfilter. CO₂ was absorbed in the same manner as in the oxygen/ozoneincubator.

The control and the oxygen treatment incubators were set to 99.50 F±0.50F and 60%±2% relative humidity for the first eighteen days and 70%±2%relative humidity for the last three days. Gas transport turnover perincubator was at the rate of about six liters per hour. The top-mountedambient air outlet 20 was adjusted to permit ambient air intake throughthe partially opened, filtered damper 16 of air inlet 18 to achieve anaverage oxygen concentration of 39% in the oxygenated incubator 10 with0.21 grams of ozone per liter of oxygenated recirculated air. Inlet 18communicates with internal fan/heater 45 of incubator 10 for circulationof heated ambient air therein. Carbon dioxide was controlled to aconstant <0.5% above ambient levels throughout the tests. Pressure wasadjusted by opening the damper 16 of air outlet 20 and damper 17 ofinlet 18 until ambient pressure was achieved. The units were operatedimmediately after loading for a period of twenty-eight hours.Immediately afterward the oxygen source 34, UV ozone generator module 36and compressed air source 49 were deactivated. Air intake dampers 17 forboth systems were opened and air outlet dampers 16 were left in theclosed position. Valves 46 of air bleeder lines 48 were left about 10%open. Air bleeder line 48 feeds air from compressed air source 49 intoincubator 10. Eggs are located on racks 50. Incubator humidity iscontrolled by the addition of water through water inlet 52 into watercollection tray 54 in incubator 10.

Vacuum pump 56 communicates with incubator 10 through line 58 andfacilitates a negative pressure environment within incubator 10. Vacuumpump 56 may be, for example, a Cole Parmer rotary vane high vacuum pump,Model H-74300-65. The vacuum created is preferably between about 2.0inches of mercury and about 29.99 inches of mercury. Note that vacuumpump 56, and at least one of compressed air source 49 and pressurizedoxygen source 34 are employed when sequential application of bothpositive pressure and negative pressure to incubator 10 are desired. If,however, only negative pressure is desired, only vacuum pump 56 isemployed. If only positive pressure is desired, only pressurized oxygensource 34 and/or compressed air source 49 are employed. Air pressure ofup to 35 PSI is attained with the above configuration.

The eggs hatched on the twenty-first day from commencement ofincubation. Oxygen/ozone treated eggs began hatching about eight hoursbefore controls.

Example 13

The following examples illustrate the non-invasive addition of chemicalsother than oxygen and ozone through the egg shell without compromisingthe structural integrity of the shell. One thousand fertilized eggs wereheld as controls and one thousand treated according to the protocol ofExample 1.

A 1/2 inch diameter porous bandage was saturated on the adsorption padwith 0.8 milliliter distilled water and 0.3 milliliter of Omaha VaccineCompany, Marek's disease vaccine and affixed to the rounded top (pointof highest porosity) of each of the one thousand eggs to beforce-enriched with oxygen/ozone.

Two hundred fifty control and two hundred fifty oxygen-treated andforced-vaccinated eggs were destroyed after fourteen days and theembryos tested individually for positive and negative vaccine. The otherfive hundred were hatched after twenty-one days from initiation ofincubation.

The above results clearly demonstrate the feasibility of obtainingeffective vaccinations through the pores of the fertile egg withoutsustaining losses incurred during the traditional invasive vaccinationsof hatched chicks.

The advantages of vaccinating through the shell is further intensifiedwhen combined with forced enhancement of oxygen methods. Almost any formof vaccination suitable for chicks can be accomplished by methodsdiscussed in the present invention.

Example 16

Growth promoters, including antibiotics and micronutrients, are alsoeffectively conveyed non-invasively through the shell withoutcompromising the structural integrity of the shell, thus favorablyinfluencing hatch rate, early chick survival and increased feedconversions. Gallimycin was introduced under same conditions as Example6, using the same dosages as in Example 13.

Positive pressure and vacuum lines 102 and 104,respectively, separately communicate with the cup 106 of the cupapparatus 100, as shown in FIGS. 7A through 7H. Line 102 appliespositive fluid pressure from a source known in the art, and fluid line104 applies negative fluid pressure from a vacuum source known in theart. However, it is understood that a single line could be employedwhich alternately supplies both positive and negative pressure to cup106 through the use of a valve which alternately communicates thepositive pressure source to cup 106 and the negative pressure source tocup 106.

Suction cup apparatus 100 has a center plenum 108 for enabling fluidtransfers between the cup 106 and egg. The positive pressure and vacuumlines 102 and 104 communicate through the center plenum 108 of the cup106 with on and off valves 110 and 112, respectively, which may beoperated independently by hydraulic or electronic actuation well knownin the art. Preferably located within positive pressure line 102, andmost preferably adjacent center plenum 108 of cup 106 is fluid atomizer114. Fluid atomizer 114 may be Model No. 42242B, manufactured bySpeedaire by Dayton Electric Manufacturing Company, Chicago, Ill. 60648.Atomization, or misting, of the fluid in positive pressure line 102increases the infusion of the fluid into the air sac of the egg due tothe increased surface area of the fluid which allows the pressure toaffect a proportionally greater amount of the fluid, and due to thedecrease in size of the particulated fluid which more readily passesthrough the egg shell pores.

FIG. 7A shows the cup apparatus 100 prior to engagement to the shellsurface. FIG. 7B shows the apparatus 100 immediately after engaging thesurface, with negative pressure being applied through line 104. FIG. 7Cshows the egg air sac emptied by negative pressure, with the air of theair sac passing through line 104 of the cup apparatus 100. FIG. 7D showsthe emptied air sac and the cup 106 being pressure-fitted more snugly todeliver the positive pressure fluid treatment through line 102commencing at FIG. 7E. FIG. 7F shows the air sac being filled throughline 102 with treating agent until full at FIG. 7G, whereupon the addedpressure fit is released and the egg disengaged at FIG. 7H.

Using the above apparatus 100, the egg may be engaged by the contactdevice and positive and/or negative pressure applied. If the pressure isnegative, the air sac will be emptied through line 102 until it conformsto the inside of the egg shell. After emptying the air sac, treatingagents such as oxygen and/or ozone, antibiotics, growth promoters,hormones, micronutrients and vaccines may then be introduced underneutral or positive pressure through line 104. If positive pressure isapplied, such as in a fluid stream, then the apparatus can be heldagainst the egg to permit positive pressure to build and force treatingagents through the pores. This action can be continued until the air sachas been refilled with the desired treating agent.

Treatment may be limited to negative pressure, ambient pressure,positive pressure, or combinations thereof For example, Examples 1, 3,6, 7 and 8 with treating agents selected from any or all of thosedescribed in foregoing examples may be employed with the aboveapparatus.

An advantage to the present treatment is that the egg can be "candled"by illuminating the egg with a light source 116, as shown in FIG. 7D,while being processed in order to view the condition of the air sac.This resulted in the ability to shorten the process times of Example 1as follows: the 28.5 inches of mercury vacuum cycle was run until theair sac conformed to the inside of the egg shell, approximatelytwenty-five seconds, and a hold time at 28.5 inches of mercury ofapproximately forty seconds was used; release of the vacuum with oxygenand/or ozone (time until neutral pressure) was approximately fifteenseconds; the pressure was increased to thirty-two pounds per square inchfor approximately forty-five seconds, until the air sac had returned toat least original size; and release of pressure to ambient wasapproximately fifteen seconds. The total time of the Example 1 protocolwas reduced to approximately two hours and twenty minutes.

Standard incubation protocols of processed eggs is applied to eggs aftertreatment.
